Synergistic Activation of Nitrite and Thiocarbonyl Compounds Affords NO and Sulfane Sulfur via (Per)thionitrite (SNO /SSNO ).

(Per)thionitrite (SNO /SSNO ) intermediates play vital roles in modulating nitric oxide (NO) and hydrogen sulfide (H S) dependent bio-signalling processes. Whilst the previous preparations of such intermediates involved reactive H S/HS or sulfane sulfur (S ) species, the present report reveals that relatively stable thiocarbonyl compounds (such as carbon disulfide (CS ), thiocarbamate, thioacetic acid, and thioacetate) react with nitrite anion to yield SNO /SSNO . For instance, the reaction of CS and nitrite anion (NO ) under ambient condition affords CO and SNO /SSNO .
